Pat, I always love your posts, they are so entertaining. We needed a wc for my DH and I'd tell them as soon as we boarded and again prior to landing, most times it worked out, but we have been stuck a few times with no one there to meet us. I have had to commandeer a wc and get us to our next departure. I always write the airline with the problem and they give me miles for compensation.
Thanks for all your great posts, always a pleasure.
